linux(ubuntu)环境搭建docker-registry

要求

docker version 1.6.0以上

1. 创建docker仓库数据和配置目录

sudo mkdir -p /opt/docker/registry/data
sudo mkdir -p /opt/docker/registry/conf

2. 创建registry容器并挂载到/opt/docker/registry/data下

sudo docker run -d -p 5000:5000 \
-v /opt/docker/registry/data:/var/lib/registry \
--name docker-registry registry:2.6.2

3. 给registry 添加用户

apt-get install apache2-utils \
htpasswd -c /opt/docker/registry/conf/docker-registry.htpasswd rennbon

添加完一个用户后再添加其他用户不需要 "-c"

4. 获取SSL证书

网上很多用openssl生成证书的方法，我这里也照着试用了下，但是因为不被信任等问题导致docker login失败，这里主要通过letsencrypt生成证书

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto --help

这里菜兄我碰到了如下问题

OSError: Command /opt/eff.org/certbot/venv/bin/python2.7 - setuptools pkg_resources pip wheel failed with error code 2

"解决方法"
pip uninstall virtualenv
pip install virtualenv

给自己的域名生成证书

./letsencrypt-auto certonly --standalone -d <HOST>

执行成功后出现以下目录

/etc/letsencrypt/live/<HOST> 目录

然后执行copy,将公钥和私钥copy到当初建造了registry配置目录下，当然这里也可以不copy，在下面的Nginx代理的时候挂载当前目录
cp /etc/letsencrypt/live/<host>/fullchain.pem  /opt/docker/registry/conf/docker-registry.crt
cp /etc/letsencrypt/live/<host>/privkey.pem /opt/docker/registry/conf/docker-registry.key

5. docker nginx 代理

sudo docker run -d \
-p 443:443 \
--name docker-registry-proxy \
-e REGISTRY_HOST="docker-registry" \
-e REGISTRY_PORT="5000" \
-e SERVER_NAME="<host>" \
--link docker-registry:docker-registry \
-v /opt/docker/registry/conf/docker-registry.htpasswd:/etc/nginx/.htpasswd:ro \
-v /opt/docker/registry/conf:/etc/nginx/ssl:ro \
containersol/docker-registry-proxy

6. 远程登录宿主机docker registry

docker login <host>
Username:
Password:
Login Succeeded
